If we consider our environment as our basis of life, then its protec-tion must be our highest priority.
BIOGAS
BIOGAS - Pioneering a cleaner environmentBiogas storage systems are an active contribution to renewable energy production and thus a key contribution to a cleaner environment.
Sattler and Ceno have a long-standing tradition of designing solutions for the storage of biogas, substrates, and fermentation residues. Sattler invented the double membrane gas holder for digester gas from sewage treatment plants back in 1981. This storage solution has been tested and proven over decades and meanwhile become a key component of modern sewage treatment plants worldwide.
As a leading provider in this field, we are eager to keep the full supply chain within our own hands. Our weaving and coating lines ensure top quality in providing the base material – PVC-coated polyester fabrics.

Double membranegas storageThe Sattler double membrane gas holder consists of a formative outer membrane and of an internal and a bottom membrane forming the actual gas space. A permanently running support air blower provides air to the space between the membranes to keep the pressure constant – balancing apossible inflow or outflow of gas.
The pressurized air keeps the outer membrane in shape and allows the gas holder to withstand external loads. At the same time, the inner membrane is put under pressure and gas is pushed into the gas ducts.
A widely visible trademark of the Sattler double membranegas holder is the patented Air Flow SystemTM. It ensures a uniform air intake across the height of the gas holder. Ultra-sonic and rope length measurement are used to determine the filling level inside the tank. To improve measurement accuracy, the inner membrane is manufactured as to ensure reproducible membrane movement.

Important features:
The tank-mounted double membrane gas holder consists of an outer membrane and an inner membrane that seals the fermentation space gas-tight.
The outer membrane is reinforced by a support air blower. This is to maintain the internal pressure at a constant level and to ensure to withstand wind and other outer forces (loads).Much like the DMGS, this gas holder type also uses the patented Air Flow SystemTM. Both membranes are anchored to the crown or to the outer wall of the steel or concrete tank using clamping rails with a positive and non-positive fitting. The positive fitting is secured by a rope welded into the outer rim of the membrane.
The substructure prevents the inner membrane from touching the substrate and being destroyed by the agitators. The belt-structure and central pole are designed to withstand the required loads. Various openings ensure the perfect operati-on and servicing.

Biogas roofThe single-shell tank-top biogas roof consists of an outer mem-brane resting on a central pillar. This allows the biogas roof to withstand external forces, such as snow, rain, wind loads etc. The biaxial curvature of the surface prevents the roof from fluttering and pumping in the wind. The membrane is fastened to the top of steel or concrete tanks in order to form a gas-tight sealing. Safety valves secure the covering against over- or underpressure on the gas side. The double-shell biogas roof is a mast-supported tank cover consisting of an inner membrane forming the actual gas space. Similar to a tent, the outer membrane is stretched between the central pillar and the outer edge of the tank. This ensures an even pretension of the membrane and a reduced wear and tear around the edge of the tank.

Gas bagGas bags can be manufactured in many different shapes as for ex-ample cylindrical or rectangular to fit your needs. These depressu-rized gas holder systems are mounted inside buildings or in steel or concrete tanks. Their shape is frequently determined by the space available around them. Cylinder shapes are mounted horizontally in buildings or suspended inside steel or concrete tanks. Gas bags are mostly filled and emptied via outlets in the stable top or bottom surfaces. Level metering is done using rope length systems. To improve measurement accuracy, the gas bags can be loaded with weights. This ensures an even movement of the membrane. Gas bags must generally be encased to withstand all kinds of external loads.

Important features:
Silo roofThe tank-top silo roof helps prevent emissions and the contamination of fermentation residues with rainwater. It offers the ideal solution for low-e-mission tank coverings. The roof has been designed to withstand extreme wind loads as well as snow and water loads. Its material-specific design has led to a characteristic shape. It prevents the roof from fluttering and pumping with the wind while also reducing material fatigue. Due to the very low level of emissions, it is also a great contribution to a cleaner environment.
The silo roof is distinguished by a highly sophisticated multi-functional design, which makes it the ideal solution for agriculture and for sewage treatment as well as biogas plants.

Importantfeatures:
Silage lagoons are a low-cost solution for storing substrates and fermentation residues. They are highly customizable to meet all kinds of location requirements, both in terms of size, shape, and operation of the lagoon. When it comes to ensuring even lower emission levels, our tested and proved floating covers should be used. Moreover, the silage lagoon is equipped with an integra-ted high-volume gas holder upon request. They function as a post-fermenter and/or fermentation residue storage tank both in the construction of new and in the re-equipment of existing lagoons. Special service and operating platforms ensure an optimal management of the lagoon.
We have been specialising in slurry silage lagoons for over two decades and are certified accor-ding to JGS since 2002. Due to the high quality of our materials and up-to-date manufacturing and welding processes, we have meanwhile hundreds of silage lagoons in operation to the fullest satisfaction of our customers.
A special form of silage lagoons in our portfolio is dedicated to the storage of beet pulp. In these lagoons the stored substrate consists of crushed beetroot. The special design of the PE sealing foils allows for an ideal withdrawal of the substrate at a predefined station. To achieve this Ceno designed a special pump trolley, which may be moved across the dam of the silage lagoon and immerged in the substrate. The pump is mounted on the trolley to ensure the automatic inflow and outflow of gas from and to fermenter tanks.
